This is a 16TB Seagate Exos X16 Hard Drive with model number ST16000NM001G-2KK103 and serial ZL2NQDYD.
I bought this drive new in 2022, and have been running it in my NAS with 0 bad blocks or read errors, in an air conditioned, non-smoking home. I had weekly scheduled Quick SMART tests, and yearly Extended tests, and never had a problem show up.
Also, I have multiple drives for sale, so check out my other items.
I pack well and ship fast. Check my feedback then buy with confidence!
Here's the output from smartctl, run minutes before powering off the NAS and pulling the drive:
